Research Description: Prof. Robert G. Brown is interested in using algebraic and statistical methods to study a wide range of equilibrium and nonequilibrium problems. With collaborator Dr. Mikael Ciftan, Dr. Brown has developed new Monte Carlo Langevin equation-based techniques that allow dynamic/nonequilibrium and static/equilibrium phenomena to be studied on the same footing. His recent work includes algebraic and computational studies in dynamic and static critical phenomena in quantum optics and magnetism. In earlier work, Dr. Brown also developed a generalized (non-muffin-tin) stationary multiple scattering theory including applications to band theory and quantum chemistry. This work formally eliminates the muffin-tin approximation from KKR-type band theory and its equivalents in quantum chemistry, without the need for so-called "near field" corrections.

(December 2003 to present) (A list of column titles and topics follows.
The column itself was initially called
"Cluster Kickstart", which explains the focus
on topics for the beginner. In January, 2005
the column's name was changed to "Cluster
Edge" and topics are more free ranging..) .

component of standard Linux? Tools with a
library interface could optimize in many
useful ways, and automagic resource aware
cluster schedulers would finally become possible.) .
